【摘要】 在力学参数测试的基础上,对钛波槽管进行了疲劳强度和静载强度分析;对应力集中部位进行了有限元数值计算。通过分析和计算,得出结论:冷凝器在正常运行条件下,钛波槽管能满足疲劳及静载强度要求;各种载荷引起的应力中,由温度差所产生的热应力比较大。为了使冷凝器更安全,有必要在壳体端部装设膨胀节以减小热应力。在合理设计槽形并具有良好的波槽成型工艺下,用钛波槽管作为冷凝器的冷却管是安全的。更多还原

【Abstract】 On the basis of mechanical parameters test,the fatigue strength analysis and static load strength analysis of the Titanium circularly-grooved tube were made.In addition,the numerical calculation of the stress concentrated parts was done by the finite element method.From the analysis and calculation,the conclusions were as follows: at the condition of the condenser was normally operating,the Titanium circularly-grooved tube could fulfill the requirements of the fatigue strength and static load strength;The thermal stress was relatively large in the resulted stresses from various loads.For a condenser more safe,it is necessary to equip the expanding node at the end of condenser shell to decrease the thermal stress;Titanium circularly-grooved tube applied in the condenser was safe only if the groove was designed properly and the shaping technique of the circular groove was very well.更多还原
